摘要： A system for saving the architectural state of a processor is described. The system performs a save state operation, which involves, for each sector in a set of sectors of the architectural state, determining whether the architectural state for the sector has already been saved to a memory, and saving the architectural state for the sector to the memory when the architectural state for the sector has not already been saved to the memory. Each sector in the set of sectors comprises a different and separate portion of the architectural state of the processor. The system determines whether the architectural state for a given sector has already been saved to the memory by checking a needs-rinsing flag for the given sector.The needs-rinsing flag for the given sector is asserted upon modifying the given sector and cleared following the save state operation.

摘要： Methods, systems, and media are provided for power management. The power management includes, but is not limited to storing at a computer system a history of canceled entries into a low power state that interrupted a transition of the unit from an active mode to the low power state and disallowing transition of the unit into the low power state when a number of canceled entries indicated by the history of canceled entries exceeds a canceled entry threshold.

摘要： Power gating decisions can be made based on measures of cache dirtiness. Analyzer logic can selectively power gate a component of a processor system based on a cache dirtiness of one or more caches associated with the component. The analyzer logic may power gate the component when the cache dirtiness exceeds a threshold and may maintains the component in an idle state when the cache dirtiness does not exceed the threshold. Idle time prediction logic may be used to predict a duration of an idle time of the component. The analyzer logic may then selectively power gates the component based on the cache dirtiness and the predicted idle time.

摘要： The described embodiments include a computing device with one or more entities (processor cores, processors, etc.). In some embodiments, during operation, a thermal power management unit in the computing device uses a linear prediction to compute a predicted duration of a next idle period for an entity based on the duration of one or more previous idle periods for the entity. Based on the predicted duration of the next idle period, the thermal power management unit configures the entity to operate in a corresponding idle state.
